Parahydrogen-induced polarization in alkyne hydrogenation catalyzed by Pd nanoparticles embedded in a supported ionic liquid phase.
TL;DR: Parahydrogen-induced polarization was observed in the gas phase heterogeneous hydrogenation of propyne catalyzed by Pd(0) nanoparticles embedded in an ionic liquid phase supported on activated carbon fibers, demonstrating the important role of the ionic Liquid.

Parahydrogen and synthesis allow dramatically enhanced nuclear alignment
TL;DR: The PASADENA effect as mentioned in this paper is a method for transient high-sensitivity proton spin-labelling by molecular addition of dihydrogen, which can be converted to magnetization observable by NMR.
Transformation of symmetrization order to nuclear-spin magnetization by chemical reaction and nuclear magnetic resonance.
TL;DR: A method of obtaining very large nuclear-spin polarizations and a means of extending the resultant sensitivity enhancement to other spins is proposed in which the transfer of order occurs through population differences not associated with magnetization.
Net NMR alignment by adiabatic transport of parahydrogen addition products to high magnetic field
TL;DR: In this article, a field-cycling method is demonstrated whereby the nuclear spin order of para-enriched H2 is inserted adiabatically into a product molecule formed by molecular addition.
